Giffuni from comment #7) Relative to increasing swap on a RPi2B V1.1 and its 1 GiByte of RAM, I'll reference: https://lists.freebsd.org/pipermail/freebsd-hackers/2018-January/052165.html which is an example of pfault/vmwait mixure hangups during buildworld when top shows: Swap: 2048M Total, 52M Used, 1996M Free, 2% Inuse The RPi2B V1.1 was getting the report: warning: total configured swap (524288 pages) exceeds maximum recommended amount (405460 pages). So, the hangup is apparently an example of the "man 8 loader" note: Note that swap metadata can be fragmented, which means th= at the system can run out of space before it reaches the theoretical limit. Therefore, care should be taken to not configure more swap than approximately half of the theoretical maximum. ctfmerge is not the only place that people have trouble with self-hosting based on 1 GiByte of RAM for a 32-bit architecture. --=20 You are receiving this mail because: You are the assignee for the bug.=
